How to Configure IPTABLES to allow PTP sync behind a bridge firewall

We have a Fedora machine with eth0(ip:10.321.xx)connected to intranet. The same machine has a eth1 with a few more linux boxes connected in a 192.xx network. on the 10.321.xx n/w there is a PTP server. But I cant seem to get PTP time sync to work on any machines on the 192.xx n/w. I AM able to ping the PTP server from the 192.xx network machines. These are some configurations. I've disabled my normal rules just to get this to work. Thanks for all the help !

I tried adding port 319/320 explicitly, to no avail. I tried adding mcast explicitly , to no luck. i
